AbstractIn this paper，Melastoma dodecandrum of 15 different regions was used as the experimental material to evaluate and analyze the growth morphological diferences，and cluster analysis was used as the main statistical method to preliminically classify the Melastoma dodecandrum germplasm resources， which provided certain theoretical basis and technical reference for the application of Melastoma dodecandrum in landscape architecture and the breeding of excellnt varieties.The results showed that： （1）Melastoma dodecandrum materials in Baiyun area of Guangdong had narrower and longer leaves，and at the same time had the characteristics of larger flowers in ful bloom; （2）the materials in Zengcheng area of Guangdong had larger flower diameters，dusher flower colors，and taller plants； （3）the Melastoma dodecandrum materials in Qinzhou area of Guangxi，Fangchenggang area of Guangxi， Ningde area of Fujian， and Yangjiang area of Guangdong had reddish bright flower colors and larger stomatal areas； （4）the Melastoma dodecandrum materials in Guilin， Guangxi， Longyan area ofFujian， Liuzhou area of Guangxi， Zhangzhou area of Fujian， and Wuzhou area of Guangxi were classified into two types of Melastoma dodecandrum germplasm resources，one of which was the most important one in the study of the Melastoma dodecandrum germplasm resources，and the other was the most important one， Zhangzhou， Guangxi， Wuzhou， Jieyang， Guigang， Guangxi， Hechi，and Heyuan in Melastoma dodecandrum.In conclusion，the morphological characteristics of Melastoma dodecandrum germplasm resources from these diferent regions can be used as the theoretical basis for their application to different landscaping needs.
